* Host-thread safety, enabling OpenCL commands to be enqueued from multiple host threads; * Sub-buffer objects to distribute regions of a buffer across multiple OpenCL devices; * User events to enable enqueued OpenCL commands to wait on external events; * Event callbacks that can be used to enqueue new OpenCL commands based on event state changes in a non-blocking manner; * 3-component vector data types; * Global work-offset which enable kernels to operate on different portions of the NDRange; * Memory object destructor callback; * Read, write and copy a 1D, 2D or 3D rectangular region of a buffer object; * Mirrored repeat addressing mode and additional image formats; * New OpenCL C built-in functions such as integer clamp, shuffle and asynchronous strided copies; * Improved OpenGL interoperability through efficient sharing of images and buffers by linking OpenCL event objects to OpenGL fence sync objects; * Optional features in OpenCL 1.0 have been bought into core OpenCL 1.1 including: writes to a pointer of bytes or shorts from a kernel, and conversion of atomics to 32-bit integers in local or global memory.
